Helminth parasites of the cunner (Tautogolabrus Adspersus (Walbaum)) in Newfoundland

Abstract

A total of 808 specimens of the labrid Tautogolabrus adspersus (Walbaum), obtained during the months of August 1967 to September 1967, and July 1968 to October 1968, from eight sampling areas around the Newfoundland coast were examined for helminth parasites. -- Of the 21 different helminths recovered, 18 are from a new host. All species found are described and discussed. Data were analyzed quantitatively to note any variations in infection levels among the different sampling areas and locations within the areas. -- The degree of infection with Cryptocotyle lingua (Creplin, 1825) metacercariae on various parts of the body was noted, so was the infection per unit area, and the incidence of parasitaemia in the different areas sampled. -- An increase in the number of species of helminths and in the intensity of infection was found to parallel increasing age.
